In recent years, the role of distributed generation has significantly increased not only as power generator, but also as an important factor in power quality improvement. In this paper, a method is proposed for reducing the voltage imbalance while the DG is connected to the grid. Control loops pertaining to active and reactive powers are provided in order to control the injected power to the grid. Besides, the virtual impedance loop and proportional–resonant controller are also utilized in the control loop. The simulation results confirm the functionality of the control strategy and the controllers in eliminating the imbalance

In this paper the pole placement idea is employed to propose a controller for the AQM in a IP router. Our Self–Tuning RED and Proportional–Integral controller based on Pole Placement can assign proper ranges of the damping ratio ξ  and the undamped...

This paper introduces modeling of the probabilistic dependence between different structures of power system devices, employing the “Copulas” analytical tool for correlating among multivariate outcomes. Copulas have become a popular analytical tool in...

Current methods for automatic feedback control of functional electrical stimulation (FES) employ classical techniques, and require much trial–and–error calibration. Given the nonlinear and time–varying nature of the system, there is a need for more...

Dangers resulting from sudden changes of theangle of twist in airplanes, especially during the landing led theresearchers to find a solution for this problem. On one hand,one of the most important issues about planes' dynamics hasbeen designing a...

The growing concern about the power quality im–provement associates with the recent increase in the loads which produce high PQ disturbances as well as the increase in the loads which are sensitive to PQ disturbances. One important aspect of PQ...
